Caralluma hirtiflora N.E.Br.
Hairy-flowered Caralluma
A species described by N.E. Brown, distinguishable by the short stiff hairs covering the floral lobes — an unusual character within the genus that justifies its specific epithet (hirtiflora = with hairy flowers). Inhabits dry savannah and scrubland zones of eastern and southern Africa, usually on rocky soils or among rocky outcrops. Stems are medium-sized quadrangular, greyish-green.
